Default File Name for Mail Formats

To avoid naming conflicts and problems with long file names, KeyView applies its own names to the extracted mail folders and mail items when a name is not supplied in the call to ExtractSubFile. A non-mail attachment retains its original file name and extension.

When the contents of a mail store or the message body of a mail message are extracted, the extracted file names might include the following:

  • The first valid eight characters of the original folder name or "Subject" line of the mail message. If the "Subject" line is empty, the characters kvext are used, where ext is the format's extension. For example, the characters would be "kvmsg" for MSG, and "kvnsf" for NSF.

    The following special characters are considered invalid and are ignored:

    • any non-printing character with a value less than 0x1F
    • angle brackets (< >)

    • asterisk (*)

    • back slash (\)

    • colon (:)

    • double quote (")

    • forward slash (/)

    • pipe (|)

    • question mark (?)

    For notes, the file name is derived from the first 24 characters of the note text. For contact entries, the file name is derived from the full name of the contact.

  • The characters _kvn, where n is an integer incremented from 0 for each extracted item.
  • One of the following extensions:

    Type File Extension
    email message .mail
    .rtf
    (NSF files)
    calendar appointment .cal
    contact entry .cont
    task entry .task
    note .note
    journal entry .jrnl
    distribution list .dist

    If the type cannot be determined for an MSG or PST file, the file is given a .mail extension.

    If the type cannot be determined for an NSF file, the file is given a .tmp extension.

For example, an MSG mail message with the subject line "RE: Product roadmap" that contains the Microsoft Excel attachment release_schedule.xls is extracted as:

RE produ_kv0.mail
release_schedule.xls

If an extracted message contains an embedded OLE object or any attachment that does not have a name, the object or attachment is extracted as _kv#.tmp.
